  • Creativity
  • Flourishing of the arts & sciences
  • Berlin became the cultural centre of Europe
• Cinema


  • Fritz Lang directed the film Metropolis - technically very advanced
  • Marlene Dietrich became a global star

  Showed that designs should be modern and practical
• Artists


  • Otto Dix and George Grosz believed that art should show the reality of everyday life
• What forms can chemical energy convert into?

  Kinetic energy or thermal energy
• What role do batteries play in chemical energy storage?

  Batteries store chemical energy for devices
• Why does a book on a shelf have gravitational potential energy?

  Due to its height above the floor
• What does elasticity refer to in materials?

  The ability to stretch or compress and bounce back
• What happens to the elastic potential energy in a rubber band when it snaps back?

  It is converted into kinetic energy
• How is magnetic energy generated?

  By magnets or moving charges
• How does magnetic energy differ from chemical energy and kinetic energy?

  Magnetic energy is associated with magnetic forces, unlike chemical energy in bonds or kinetic energy from motion
• How does electrostatic energy change when charges are brought closer together?

  It increases as charges get closer
• What is a Chemical Energy Store?

  Energy stored within chemical bonds
• What happens during nuclear fission?

  It splits heavy nuclei into lighter ones
• What happens to gravitational potential energy when water flows downward from a dam?

  It is released as the water flows down
• If a heavier object moves faster, what can be said about its kinetic energy?

  It stores more kinetic energy
• What happens to chemical energy when bonds are broken or formed?

  It can be released or absorbed
• What type of energy is produced when chemical bonds are broken?

  Kinetic energy or thermal energy
• What is a Magnetic Energy Store?

  Energy present in a magnetic field
• How does the motion of particles affect thermal energy?

  Faster particle motion increases thermal energy
• How do plant leaves utilize chemical energy?

  They store energy from the sun through photosynthesis
• How does elastic potential energy differ from chemical and gravitational potential energy?

  • Elastic potential energy: Stored through physical deformation
  • Chemical energy: Stored in bonds
  • Gravitational potential energy: Based on position
• How does food relate to chemical energy?

  It contains chemical energy for bodily functions
• When is elastic potential energy released?

  When the material returns to its original shape
• What is a Magnetic Energy Store?

  The energy present in a magnetic field generated by magnets or moving charges
• What happens to electrostatic energy when the magnitudes of the charges are higher?

  It increases with higher charge magnitudes
• What is the relationship between height and gravitational potential energy?

  Higher height results in more potential energy
• What are the two main types of nuclear reactions?

  • Nuclear fission: splits heavy nuclei into lighter ones
  • Nuclear fusion: merges lighter nuclei into heavier ones
• How do static charges on hair create an electrostatic energy field?

  They cause hairs to repel each other
• How does nuclear energy differ from chemical energy?

  • Nuclear energy is stored within the nucleus
  • Chemical energy is stored in chemical bonds
• What is released during nuclear fusion?

  Immense energy
• How is elastic potential energy released in a stretched spring?

  When the spring is allowed to unwind
• What is an Electrostatic Energy Store?

  Energy due to charges in a system
• What is an Elastic Potential Energy Store?

  Energy built up when a material is deformed
• What is the role of an electromagnet in a generator?

  It stores magnetic energy to produce electricity
• How does the strength of a magnetic field and the amount of magnetic energy it stores increase?

  The strength and amount of energy increase with the magnitude of the magnetic field
• What are the key concepts related to Elastic Potential Energy Store?

  • Elasticity: Ability to stretch or compress and return
  • Deformation: Change in shape or size under force
• How does nuclear energy differ from kinetic and thermal energy?

  • Nuclear energy arises from subatomic changes
  • Kinetic energy is associated with motion
  • Thermal energy is related to heat
• What type of energy do fuels like petrol store?

  Chemical energy used in vehicles
